OILSTONE-BOX.

SPECIFICATION forming part of LettersI-'atent N o. 639,343, dated December 19, 1,899. Application filed December 3l, 1898. Serial No. 70,816. (No model.)

To @ZZ whom, t may concern:

Be it known that I, WILLIAM BLACK, Jr., a subject of the Queen of Great Britain, residing at Montreal, in the district of Montreal, in the Province of Quebec, Canada, have invented a new and useful Improvement in Oilstone-Boxes, of which the following is a speciiication.

My invention relates to improvements in oilstoneboxes; and the object of the invention is to devise an oil-receptacle to be attached to the inside of the lid of the box, whereby on opening the box the stone isv always left oiled and ready for use; and it consists, essentially, of a receptacle designed to be fitted inside the lid of the box, having a slightly-convex top with a suitable button attached thereto of suilicient length to rise above the lid of the box when the latter is closed, a cup attached to the lower side of the tank,with suitable apertures for the oil to pass through, and a slide controlled by the button, passing through the side of the box, so that on the pressure of this button the slide is forced back and leaves the apertures clear for the oil to pass through, the parts being arranged and constructed in detail, as hereinafter more particularly explained.

Figure l is a perspective view of the oilstone-box, showing my device attached to the inside of the lid. Fig. 2 is a perspective view of the oil-receptacle. Fig. 3 is a sectional View of the oilstone-box, showing the internal construction of my device. Fig. 4 is a cross-sectional view, on an enlarged scale, of a detail.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the oil-receptacle, which is made of flat form, so as to conveniently it inside the lid B.

C is the cup. l

c c are the apertures in the cup through which the oil passes onto the stone D.

c' is a slide which by being forced past the aperture c leaves the same open.

c3 is a spindle suitably attached to the slide o and terminating with the press-button E. The spindle csis encircled by a spring F, which by means of being placed between the button E and the cup C serves to keep the slide c in the closed position.

a is the top ofthe receptacle, which is curved in form and iits into the inside of the lid B. l

The top of the receptacle a is surmounted by a button c', which passes through the top of the lid of the box. The flange a2 is left around the edge of the receptacle, so that it may be readily attached to the inside of the lid.

The cup Gis threaded at the top and screwed into the receptacle Ct, and as this will necessarily raise a small flange inside the bottom of the receptacle l propose to have channels or openings cut in said iiange and also corre sponding channels in the top of the wall of the cup, so as to drain the receptacle a to the last drop of oil.

To fill the receptacle with oil, the cup C is unscrewed from the receptacle d, carrying the spindle c3 with it, or` if the spindle c3 is made fixed to the press-buttonvE by detaching the spindle from the slide c' the cup C is left free to be taken off. In placing the spindle cS through the orifice in the cup C a suitable rubber washer may be used to prevent leakage.

l propose in constructing the grooves o2 for slide c' to run in to have them firmly supported from the wall of the cup and., if necessary, let them form solid pieces from the edges of the slide c' to the sides of the cup.

In order to oil the stone, the box being closed, you place your thumb on the button E and a linger on the button d and by a slight pressure of both you force the slide c along the grooves c2, thereby leaving the ap ertures c c open for the oil to run through, and by the pressure of the finger on the lout` ton ct, the top ct being convex, the displacement of air forces the oil' through the apertures c c onto the stone D, so that when the box is opened the stone is oiled, and immediately the pressure on the button E is taken away, the spring F, encircling spindle c3, forces the slide c into the closed position.

Although I show the button c rising above the top of the lid, it will readily be understood that it may be made to come ush with the lid. i

What l claim as my invention is"V 1. The combination with the box having a lid, of an oil-receptacle `secured to the under face of said lid, a dischargeopening in said receptacle, a cover normally closingsaid opening, means extending through the lid for removing said cover, and a compression device for said receptacle also projecting through the lid. y

2. The combination with an oilstone-box comprising a lower portion of rectangular form having the stone seated therein and projecting above the upper edge thereof and a cover having a recess in its under face of rectangular form to Iit snugly the stone and rest upon the upper face of the walls of the bottom, of a narrow oil-receptacle of elongated form adapted to fit Within the recess of the cover and a flange adapted to be secured to the under face of said cover and the means for discharging the oil from said receptacle, substantially as described.

3. In an oilstone-boX, the combination with the lid, of an oil-receptacle connected thereto, a cup extending from such receptacle downwardly into proximity with the stone, suitable orices :in said cup, a slidable covering therefor, a spindle connected to the slidable covering and a button on the end thereof extending through the side ofthe lid and a spring interposed between the inner end of the button and the cup, and a button having the stern thereof extending through the top of the lid and operatively connected to the top of the receptacle as and for the purpose specified.

Signed at Montreal this 24th day of December, 1898.
